The Lifespan Sibling Relationship Scale (LSRS) is the most comprehensive self-report questionnaire available to evaluate the quality of sibling relationships based on feelings, behaviors, and opinions across child and adult periods of development. To the best of our knowledge, the psychometric properties of the LSRS have not been assessed or reported in an English-speaking population since this assessment tool was introduced 20 years ago. The current study examined the internal reliability and construct validity of the LSRS with a sample of 370 young adults living in the United States. Results indicated that the original six-factor model of the LSRS is plausible with minor modifications to measure the sibling relationship quality and with its close correlation between factors and scales.

寿命兄弟姐妹关系量表（LSRS）是最全面的自我报告调查表，可用于根据儿童和成人发育阶段的感觉，行为和意见来评估兄弟姐妹关系的质量。据我们所知，自20年前引入该评估工具以来，尚未评估或报告过以英语为母语的人群的LSRS的心理测量特性。当前的研究以居住在美国的370名年轻成年人为样本，检验了LSRS的内部可靠性和结构效度。结果表明，LSRS的原始六因素模型似乎是合理的，只需稍作修改即可测量同级关系质量，并且其因素与量表之间的相关性很高。
